What Would Be The Fastest Way To Add Files?

[ColBat]

I will have my DS1621+ running by late tomorrow (I hope) with two 8TB Ironwolf drives and two 16TB Ironwolf drives using SHR, all drives in Storage Pool 1. There is nothing on the drives except for what Synology/SHR installed as I added the drives to the storage pool. Once completed I should have about 29TB of available space and 14.6TB of protected space according to Synology’s RAID calculator. I will still have two open bays and I have three Ironwolf 16TB drives from my hobbled DS920+. The three drives were part of the four 16TB Ironwolf DS920+, with RAID 10. After #1 Bay failed on the DS920+ and messed up its16TB drive and the replacement 16TB installed, I got the 6 Bay DS1621+, started reformatting the drives to exFAT to remove all the previous DSM install, especially the RAID 10 configuration I used. I have reformatted the two 8TB drives and two 16TB drives (from exFAT to BTRFS) that I have installed into the DS1621+, but not the the remaining three 16TB drives. When the DS920+ failed the 2-4 Bay 16TB drives with RAID 10 continued to work and provided access to the 22TB of media stored on the DS920+. All 22TB of Media is backed up on two 16TB external hard drives.


So my question is what would be the fastest way to install my 22TB of media to the new DS1621+?

-- Use the two external 16TB hdds and USB connect to transfer the files to the installed Storage Pool on the DS1621+. Then reformat the three remaining 16TB Ironwolf drives to add two of them to the DS1621+ (Two 8TB and four 16TB), keeping the third as a spare?

-- Putting the three 16TB Ironwolf hdds back into the hobbled DS920+ (Bay2-4) then try to transfer the media from the DS920+ to the DS1621+? Is this even possible?

-- Or is there some other way that I don’t know about or haven’t considered?

Agree that these two options are possible. Basically either USB, or file transfer from the other NAS. Can't say which one is faster. Have bad experience with (other DS systems) USB3 Speed, I do not know the 1621+

By far the fastest way would have been if you In would have kept 3 empty bays in the 1621+, you could have tried to bring the 3*16TB disks from your DS920 in a separate pool and copy from there. But that is no longer possible. Theoretically, a RAID10 has the possibility to run with two disks, but you never know which ones.

Thanks EAZ1964. I thought about putting the three hdds from the DS920+ into the DS1621+ but I was gun shy because I was worried that the RAID 10 on those hdds might cause a problem with the first three hdds, SHR, already installed in the DS1621+. I can still put the three hdds back into the DS920+ (Bays 2-4 that work) and bring up that Storage Pool. Or can I take one of the 8TB hhds out of the DS1621+ and then put the three hdds (RAID 10) into the three open bays of the DS1621+ (after removing the one 8TB hhd)? Is this even possible and if so, would there be conflicts between the SHR and RAID 10 or between the Storage Pool 1 of each set of hdds?

Another possible approach I've considered is can I connect the DS920+ to the DS1621+ via a RJ45 cable (Lan 2 port to Lan 2 port) and transfer the files from the DS920+ Storage Pool to the DS1621+ Storage Pool? I recall there is some difficult having two Synologys running at the same time on a Lan (I'm guessing the DS920+ and the DS1621+ would both have to be connected to my internal Lan via their Lan port 1). If there is a way of having the two Synologys up and running at the same time would that be fastest than using USB Connect (the external hhds to the DS1621+)? I just don't know enough to determine whether what I'm thinking is possible and which way would be faster or if there is another way I don't know about.

 

[EAZ1964]

It is not ok to pull one 8TB from your 1621+, It would break the raid and leaves your data without redundancy.
Personally, I would try to bring the 920 back alive with the three disks and setup (from file explorer) the lan connection between the two, Then copy from one nas to the other.
If not possible, you are stuck with the USB solution.

 

[EAZ1964]

You connect the two nasses via RJ45, preferably on the regular lan.

 

[Rusty]

can I connect the DS920+ to the DS1621+ via a RJ45 cable (Lan 2 port to Lan 2 port)

Just configure them on a different subnet (you can use the same subnet as your LAN1 adapter as well just use different static IPs), give them separate IP addresses and use File station to mount one NAS over to another (folder to folder). Copy that way if the 920 is still functional from a raid configuration.

Thank everyone for their thoughts. I should be able to bring the hobbled DS920+ up with the three drives. So what do I do next?

EAZ1964 It sounds to me that you are proposing a windows based process. That is fine with me because I am a Windows person. How would I go about setting up the file explorer lan connection between the DS920+ and DS1621+ in Windows (what lan connection would I plug the RJ45 into, Lan 2 on both? Then how to copy?

Rusty, I kind of understand what you're suggesting, but I would appreciate a step-by-step explanation of how to do it?

 

[EAZ1964]

Sorry thatI was not clear: I do not refer to a Windows process, I mean the file manager in the NAS.
The direct copy from nas to nas is considerably faster than using a windows machine in the middle.

EAZ1964 How do I do a direct copy from NAS to NAS? I have the DS1621+ on my lan now. Do I connect the hobbled DS920+ to the lan also? or do I just connect DS920+ to the DS1621+ via an RJ45 cable and not connect the DS920+ to the lan separately? Once the hardware is set up, what software do I use to do the file transfer?

 

[EAZ1964]

I would connect both nas to the local LAN.
Then setup a cifs connection between the two NAS:

Use file station on the nas to make the copy.

You can also connect via direct cable, as Rusty explained earlier, a bit more setup, do not think the speed benefit will be noticable, unless you have the standard LAN connection heavily loaded.
